Kevin,
Did either of the FSA headsets have sealed bearings?
My Rush's stock headset has rusty non-sealed bearings in the stock headset. I'd like to switch to the FSA 1.5Z but want sealed bearings and the FSA is lighter than the Cane Creek.
Why did you use the standard cup on the bottom? I'm concerned about a flush cup on the bottom with hitting my fork on the downtube.
